NASA's Chandra Observatory has finally confirmed the evidence of jet in the Sagittarius A* (Sgr A*)- a supermassive black located 26,000 light years away from the Earth in the center of the Milky Way Galaxy.
A team of international researchers has finally solved the long standing mystery of the high speed jets that are emitted from active black holes.
Most of the universe's heavy elements, including the iron central to life itself, formed surprisingly early in cosmic history and somehow spread evenly throughout the universe, according to a new study of the Perseus Galaxy Cluster using Japan's Suzaku satellite.
A dormant volcano -- a supermassive black hole -- lies at the heart of our galaxy. Fresh evidence suggests that it last erupted two million years ago. Astronomers have long suspected such an outburst occurred, but this is the first time they've been able to date it.
New Chandra images of Sagittarius A* (Sgr A*), which is located about 26,000 light-years from Earth, indicate that less than 1 percent of the gas initially within Sgr A*'s gravitational grasp ever reaches the point of no return, also called the event horizon.
Supermassive black holes can be found in the center of galaxies, driving enormous forces that shape the space around them. Now, astronomers have found a new way to measure the spin of these black holes, paving the way for a better understanding about how they drive the growth of galaxies.
A Dartmouth-led team of astrophysicists has discovered the extent to which quasars and their black holes can influence their galaxies.
In the center of an active galaxy, a huge black hole consumes matter from its surroundings. Now, ESO's Very Large Telescope Interferometer has gathered the most detailed observations ever of the space dust around this massive black hole, revealing unprecedented details about the dust and showing sci...
By comparing infrared and X-ray background signals across the same stretch of sky, an international team of astronomers has discovered evidence of a significant number of black holes that accompanied the first stars in the universe.
The creation of new black holes was thought to be unnoticable in most cases, at least with currently available technology on Earth. But a new theory predicts that most of these invisible events could actually be detectable when looking for the right signs.
By coincidence, astronomers noticed a black hole as it "woke up" from a decades-long slumber to feed on giant planet that approached too close.
